Description Gustavo Maciel Dias Vieira 2009-04-09 02:07:27 UTC

In rawhide, g-p-m dims the display and shows a warning that the baterry is discharging when *plugging* AC power. Also, the display is brightened when the AC power is unplugged.

Version-Release number of selected component (if applicable):
gnome-power-manager-2.26.0-1.fc11.x86_64

How reproducible:
Currently, it is deterministic. 

The machine is a HP Pavilion dv4-1125br.

Comment 1 Gustavo Maciel Dias Vieira 2009-04-09 02:13:34 UTC

Actually, it seems to be a bit more complicated. The bahavior above happens when the battery is charging. If it 100% charged, g-p-m does not detect AC power status changes. It stays in the plugged and 100% charged until the next reboot.

In both situations /proc/acpi/battery/BAT0/state shows the correct state of the system.

Comment 2 Gustavo Maciel Dias Vieira 2009-05-01 18:01:48 UTC

The problem persists in the Preview Release. It's improved a bit, the icon now correctly display the status (a little plug or just the battery). But, the message about the battery discharge and the dimming of the screen continue reversed.

Current version: gnome-power-manager-2.26.1-2.fc11.x86_64

Oh, and this is a regression. It worked perfectly in F10.

Can you try installing https://admin.fedoraproject.org/updates/F11/FEDORA-2009-5740 and https://admin.fedoraproject.org/updates/F11/FEDORA-2009-5728 and then reboot please. If it fixes things, please report that as positive karma for the update. Thanks.

Comment 4 Gustavo Maciel Dias Vieira 2009-06-03 17:28:08 UTC

The problem persists with these updates.

The problem I reported in comment #1 seems very similar to bug #499948. In this case (100% charged) both /proc/acpi and hal shows the correct state. "devkit-power --dump" shows the battery as charged even without AC power.

Regarding the original problem, a battery discharge message is still displayed when puggling AC, but the screen does not dim. Actually, the screem seems to be always fully lit no matter what happens now (may be a configuration problem, but I have not touched the settings).

Comment 5 Bug Zapper 2009-06-09 13:31:05 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
